Hints and tips

 

 

 

 

 

Coding text

· Use a COMMENT command. Remember that different fonts of a given point size are

 

 

not necessarily the same physical size.

 

 

· Be aware that vertical error messages, generated when the system calculates that too

 

 

much text has been specified for placement in a box, are an approximation.

 

 

· Use the TEXT SPACED AT command to force exact text placement.

 

 

· Avoid placing too many small characters in one area of the page.

 

 

· Avoid overlapping characters to achieve bolding or other effects. Use the correct

 

 

font whenever possible.

 

 

 

· Avoid too many font switches on the same text line. This creates overhead in the

 

 

printing process.

 

 

Coding sections · Use a COMMENT command.

·Use coordinates based at 0,0 when defining a section. Then place the section at the locations you want.

Source copy

If the source filename (.FSL) and the form name (the name that follows the FORM

 

keyword) do not agree, an .FSL file is created that has the same name as the form name.

 

Therefore, when you copy X.FSL to Y.FSL and compile Y.FSL without changing the form

 

name in Y.FSL, the original X.FSL is deleted and a new X.FSL is created from the Y.FSL

 

source. Furthermore, the form file (.FRM) that is created is X.FRM and not Y.FRM. If you

 

wish to create a distinct source using another .FSL as a base, you need to change the

 

form name to the same name as the source name, or to some other name that does not

 

already exist. Two files with the same name and type cannot reside on the system.

Image complexity factors

Form design is limited by physical restrictions on the amount of image data (characters and lines) that can be printed on a scan line and on a page.

Line tables

Forms Description Language (FDL) line tables are internal FDL data structures that provide a record in memory of the lines to be drawn on a page. These tables allow the system to find the corners and edges of boxes when they are referenced later.

Since excessive amounts of memory would be required to store every line, the FDL compiler retains only the memory of the longest lines that pass through any given coordinate in a particular direction. FDL replaces dotted or broken lines with an invisible line of the same length.

Line table limits The FDL line tables can store 1,999 vertical and 1,999 horizontal lines in memory. When you exceed either of these line table limits, the following message is displayed:

TOO MANY HORIZONTAL OR TOO MANY VERTICAL LINES

This message warns you that the new user-specified line cannot be retained in the table. The message is of no real consequence to you unless the new line is intended as the side of a box. In that case, the box is not found and your form may not compile.
